Looks like a very nice SM300 http://forums.watchuseek.com/f29/vintage-omega-seamaster-300m-4th-april-1967-australia-845785.html
It's a shame that there's a personal engraving on the back.....also would have liked to see movement images. Over all a nice piece, thanks for the post.
Respectable Member pascs This Omega diver watch (with or without date) is on my wish-list. There are several on the market and this one appears to be the most decent one, I think. The price is reasonable, too. Thank-you.
Respectable Member MyVintageOmega It so appears, this beautiful Omega diver watch is still on the market. What are the reasons for it? Thank-you.
Can only imagine. Perhaps the OP has not updated the status. Also the personal engrave would be an issue to many.
Respectable Member MyVintageOmega You are right. Probably the inscription is a turning point, for most of the prospective buyers. Apart from this issue, the whole watch appears to be very desirable. Thank-you.
Also......I imagine that many buyers would not move on a watch purchase without seeing the movement. Clearly the OP has not provided that in the original post.
Respectable Member MyVintageOmega More than likely, this is the reason. The seller should have made an attempt to at least include a picture of the movement. So far, I think this example is the best on the market and the price is reasonable. Thank-you.
